Implementations

impl TextHandler

pub fn new_detached() -> Self

Create a new container that is detached from the document.

The edits on a detached container will not be persisted. To attach the container to the document, please insert it into an attached container.

pub fn version_id(&self) -> Option<usize>

Get the version id of the richtext

This can be used to detect whether the richtext is changed

pub fn get_richtext_value(&self) -> LoroValue

pub fn is_empty(&self) -> bool

pub fn len_utf8(&self) -> usize

pub fn len_utf16(&self) -> usize

pub fn len_unicode(&self) -> usize

pub fn len_event(&self) -> usize

if wasm feature is enabled, it is a UTF-16 length otherwise, it is a Unicode length

pub fn diagnose(&self)

pub fn iter(&self, callback: impl FnMut(&str) -> bool)

pub fn char_at(&self, pos: usize) -> LoroResult<char>

pos is a Event Index:

• if feature=“wasm”, pos is a UTF-16 index
• if feature!=“wasm”, pos is a Unicode index

pub fn slice(&self, start_index: usize, end_index: usize) -> LoroResult<String>

start_index and end_index are Event Index:

• if feature=“wasm”, pos is a UTF-16 index
• if feature!=“wasm”, pos is a Unicode index

pos is a Event Index:

• if feature=“wasm”, pos is a UTF-16 index
• if feature!=“wasm”, pos is a Unicode index

This method requires auto_commit to be enabled.

pub fn splice_utf8(&self, pos: usize, len: usize, s: &str) -> LoroResult<()>

pub fn insert(&self, pos: usize, s: &str) -> LoroResult<()>

pos is a Event Index:

• if feature=“wasm”, pos is a UTF-16 index
• if feature!=“wasm”, pos is a Unicode index

This method requires auto_commit to be enabled.

pub fn insert_unicode(&self, pos: usize, s: &str) -> LoroResult<()>

pub fn insert_with_txn( &self, txn: &mut Transaction, pos: usize, s: &str, ) -> LoroResult<()>

pos is a Event Index:

pub fn delete(&self, pos: usize, len: usize) -> LoroResult<()>

pos is a Event Index:

• if feature=“wasm”, pos is a UTF-16 index
• if feature!=“wasm”, pos is a Unicode index

This method requires auto_commit to be enabled.

pub fn delete_unicode(&self, pos: usize, len: usize) -> LoroResult<()>

pub fn delete_with_txn( &self, txn: &mut Transaction, pos: usize, len: usize, ) -> LoroResult<()>

pos is a Event Index:

• if feature=“wasm”, pos is a UTF-16 index
• if feature!=“wasm”, pos is a Unicode index

pub fn mark( &self, start: usize, end: usize, key: impl Into<InternalString>, value: LoroValue, ) -> LoroResult<()>

start and end are [Event Index]s:

• if feature=“wasm”, pos is a UTF-16 index
• if feature!=“wasm”, pos is a Unicode index

This method requires auto_commit to be enabled.

pub fn unmark( &self, start: usize, end: usize, key: impl Into<InternalString>, ) -> LoroResult<()>

start and end are [Event Index]s:

• if feature=“wasm”, pos is a UTF-16 index
• if feature!=“wasm”, pos is a Unicode index
